I am following the lab on Microsoft learn and cannot get the system to activate having made all the connections. The error I receive is
Flow client error returned with status code "BadRequest" and details "{"error":{"code":"ChildFlowNeverPublished","message":"The workflow with id '5b85de36-0229-eb11-a813-000d3af77de6' cannot be used as a child workflow because it has never been published.

Any help gratefully received
